香港科技大学在沙田污水厂试验硫酸盐还原自养硝化反硝化SANI工艺

香港科技大学开始进行硫酸盐还原、自养反硝化硝化集成工艺的示范性试验研究，该工艺被称为“SANI"工艺。

The Hong Kong University of Science and Technology will start a large-scale test with the Sulphate reduction, Autotrophic denitrification and Nitrification Integrated (SANI) process at Hong Kong's Shatin sewage treatment works. The pilot plant will have a capacity of 1.000 cubic meter per day.

The test is to start in April 2013 and will be conducted in cooperation with the city's Drainage Services Department. The two year upscale test of the SANI process has been funded with 24.6 million HK dollar.

The SANI process has been developed in close cooperation with Delft Technical University and KWR water recycle research institute in The Netherlands.

科技的香港大學將開始與硫酸鹽還原作用，自養反硝化和硝化集成（SANI）過程中，在香港的沙田污水處理廠大規模測試。該試驗工廠將有能力為每天1.000立方米。 

該測試是開始於2013年4月，將在全市渠務署合作進行。撒尼過程為期兩年的高級測試已經投資了2460萬港元。 

撒尼過程已經制定了與代爾夫特理工大學和荷蘭的密切合作KWR水循環研究機構。

SANI工艺是与荷兰Delft大学以及KWR水循环研究学院共同合作开发的。

First pilot test started in 2004

A team from the Hong Kong University of Science and Technology (HKUST) led by Prof Guanghao Chen of the Department of Civil and Environmental Engineering will conduct the research.

According to Prof Guanghao Chen the SANI process can solve Hong Kong's long-run problem of sewage treatment: "The research on the process started in 2004, followed by a pilot test jointly hosted with the Drainage Services Department at Tung Chung between 2007 and 2010.

从科技的香港大学（科大）为首的光浩教授陈民事部与环境工程学院的一个小组将进行研究。 

据教授光浩陈撒尼过程可以解决香港的长远经营的污水处理问题：“对过程的研究开始于2004年，随后试联合主办的渠务署在东涌2007年至2010年。

Results showed that this novel technology effectively eliminated 90% of sewage sludge production, reducing the sewage treatment cost by 50 percent and space requirement by over 50 percent, and cutting down greenhouse gas emissions by 35 percent."

SANI工艺可以降低90%污泥产量，运行费用可以降低50%，占地也是降低50%，降低温室气体35%的排放量。

Triple Water Supply System
The development of the SANI process is part of an innovative research programme by the HKUST on the Triple Water Supply system that combines freshwater, seawater flushing and cooling, and water recycling systems for air-conditioning, kitchen and laundry.

The Hong Kong Airport is the first organization in the world to put the triple water supply system into use, resulting in 52% saving of freshwater demand and up to 20 million in electricity bills and of 30 million kilowatt hour, as well as a reduction of 17,000 tonnes of carbon dioxide emissions per annum, an amount tantamount to greenhouse gas emissions by 5,500 private cars.

Flushing with seawater on city scale
Hong Kong is the only city in the world using seawater for flushing on a city scale. Making an extensive use of the system, the Water Supplies Department has delivered savings of 740,000 cubic meters per day of freshwater.

The water saved in Hong Kong exceeded those recycling systems in Australia and Japan, making it one of the most efficient and cost-effective water facilities in the world.

Many awards
The research programme on Hong Kong Triple Water Supply system has received many awards already. The potential of this system using both sea water and waste water has an enormous potential for many other large cities along the Chinese coastline.

On of the awards was the IWA Global project innovation award 2012 handed out at the IWA's biannual global water conference in Busan, Korea in September 2012.

About SANI process
Conventional biological wastewater treatment processes make use of microbes to convert pollutants in water into carbon dioxide in order to clean waste water. Since microbes grow rapidly, conventional processes produce large amounts of microbes which become sludge.

The SANI process technology, uses a Sulphate-reducing bacteria. In combination with water supply plants that use sea water, the SANI process uses sulphate in seawater as the medium to oxidize and eliminate pollutants from the sewage water.

Since the microbe boasts high efficiency and low growth rate, it minimizes sludge production by 90%, hence its naming as SANI process, meaning "sludge-killing" in Chinese.


三重供水系统 撒尼进程的发展，是由香港科技大学的三重供水系统上的创新性研究项目，结合淡水，海水冲洗，冷却和循环用水系统，空调，厨房和洗衣房的一部分。 香港机场是全球第一家把三联供水系统投入使用，导致3000万千瓦时的节约淡水需求的52％，上限为电费2000万，以及减少1.7万吨每年的二氧化碳排放量，其量5500私家车无异于温室气体的排放。 用海水对城市规模冲洗 香港利用海水冲厕对城市规模在世界上唯一的城市。做一个广泛使用的系统，水务署已交付节省74万立方米淡水的日子。 保存香港的水超过了回收系统，澳大利亚和日本，使之成为最有效和符合成本效益的水利设施在世界上。 许多奖项 香港三联供水系统的研究方案已获得许多奖项了。同时使用海水和废水该系统的潜力有巨大的潜力，许多其他大城市沿着中国的海岸线。 在该奖项的是国际水协会全球项目创新奖2012交给了在韩国釜山的国际水协会的一年两次的全球水资源会议在2012年9月。 （阅读更多关于IWA-奖伸出手： 釜山IWA-2012：两位荷兰水技术荣获IWA全球innovationm奖项 - 2012年9月22日） 关于SANI过程 传统的生物废水处理工艺利用微生物污染物转化中水转化为二氧化碳以清洁的废水。由于微生物生长迅速，传统工艺产生大量微生物而成为污泥。 撒尼工艺技术，采用硫酸盐还原菌。在与使用海水供水厂结合，撒尼过程在海水中使用硫酸为介质氧化和消除来自污水的污染物。 由于微生物拥有高效率和低增长率，它最大限度地减少污泥产量减少90％，因此其作为SANI过程命名，意在中国“污泥杀人”。
